COEFEETABLET AND PROCESS OF MAKING SAME.

No Drawing.

This invention pertains to improvements in cakes composed of coffee and processes of making such cakes. Its object is to provlde coflee units, in the form of small, compact 5 cakes, which are composed entirely of coffee.

The ingredients used in forming m coffee units are roast coffee '(either groun powdered or in bean form) and coffee concentrate in liquid, ground or. powdered form.

The proportion of twenty parts coffee to one part cofl'ee concentrate has been found 'to give satisfactory results but the ratio Wlll, of course, vary as difl'erent and coffee concentrates of different degrees 16 of density are used.

In practicing my present invention I take a measured quantity of coffee, mix itlthoroughly with a smaller measured quantity of cofiee concentrate which has been sepa- 20 rately pre ared from'another body of coffee, and moul the resultant product into cakes of uniform size. I have found that coffee concentrate, in either ground, powdered or liquid form, constitutes an ideal binder for use in forming coffee into cakes. I have also found that the emplo ment of high pressures for the formation 0 such cakes is unnecessary and that such cakes may be' moulded into form by the employmentiof a pressure of approximately one hundred pounds per square'inch. v

I am aware of the fact that-heretofore plans have been suggested'for the manufacture of cakes or tablets composed ,in part of coffee and in part of various agglutmant substances employed for the pur in the coffee into more or ess com act ca es. I am also familiar with United States Patents Nos. 1,210,542 and 1 535,233 40 setting forth proposed methods of forming coifee into cakes or'tablets by utilizing to a greater or less extent certain agglutinant elements of the coffee forming the body of the cakesin process of manufacture. My present inventlon is, however, clearly distinguished from those above indicated by the. fact that my coffee units contain no ingredients whatever except cofiee, the binder itself being coffee in concentrated form; moreover, this binder is not extracted from the coffee forming the body of the cakes but isprepared from a separate lot of cofiee, the effect of mixing the concentrate with the 'cofi'eeforming the body of the cake ,bein

bind the cake into a compact mass. But the v unit is all coffee-no substance whatever I coffee and the coffee concentrate when'the two are mixed together and pressed into j cakes, but it 1s apparent that the coffee concentrate, when mlxed with the cofiee,.fills; m the spaces between the grains of coffee. and, upon the application of the pressure.

necessary to form. e cakes, the particles of the two lots of material impregnate oneI-another in such manner as to form ake o and trength to serve th I suificient density pur ses of my invention. I

T e advantages of formin coffee. into compact unitsare obvious. Eac tablet preferably contains suflicient material to make but a single cup of coffee. Commercial pack ages of coffee units may be marked so as to indicate the number of cakes contained. therein, "thus informing the purchaser as may be preparedtherefrom. The cake may contain either a single grade "of coife e,*or

different gradesin any desired proportion/Q .1 e blended in the same cake. In form in such cofiee units numbers or other sym b0 sm ybe" stamped into the face of each cake toindicate, the'exact grade of coffee or blend of coffees contained therein, thus insuring the user against misrepresentation While my-invention is hereindescribed as relating particularly to the formation of cakes composed of cofi'ee and coffee concentrate, the invention is, also applicable to various other food products which may be advantageously formed intocakes; the essence of my invention consistin in the mixing of' a'measured quantity 0 the concentrate pre ared from one body of a given comm ity with another measured quantity of said commodity and the pressing of the res'ultant product into cakes, the concentrate acting as a binder.

Oofi'ee concentrate is a term commonly appliedin the art to a water soluble extract 106 of coffee, and the term is to be so unde 1;;

tion. What I claiin is stood wherever it appears in this applica'-' ing coflee units, consisting in mixing a measured quantity of roasted disintegrated cofiee bean with a measured quantity of coffee concentrate and moulding the resultant product into cakes under pressure.

2. A coffee unit consisting of a measured quantity of roasted disintegrated coffee bean and a measured quantity of coffee concentrate intermixed, and moulded under pres- Lonnie sure, in which the coffee concentrate acts as l the binding agent.

3. A cofl'ee unit consisting of roasted disintegrated cofiee bean impregnated, enriched and held together by a cofiee concentrate.

In testimony whereof I have affixed my 15 signature.
